In order to mmap the registers used to load the firmware, the
framebuffer needs to be in "mapped" mode. So you'll need to do
something like:
int newmode, oldmode;
ioctl(fd, WSDISPLAYIO_GMODE, &oldmode);
newmode = WSDISPLAYIO_MODE_MAPPED;
ioctl(fd, WSDISPLAYIO_SMODE, &newmode);
...
ioctl(fd, WSSDISPLAYIO_SMODE, &oldmode);
(with proper error checking of course).
